Comment 2 for bug 380282

some more output from within synaptic:

dbconfig-common: writing config to /etc/dbconfig-common/serendipity.conf
*** WARNING: ucf was run from a maintainer script that uses debconf, but
             the script did not pass --debconf-ok to ucf. The maintainer
             script should be fixed to not stop debconf before calling ucf,
             and pass it this parameter. For now, ucf will revert to using
             old-style, non-debconf prompting. Ugh!

             Please inform the package maintainer about this problem.
Replacing config file /etc/dbconfig-common/serendipity.conf with new version
